FULTON COUNTY, Ga. -- Another court date has been postponed for the man accused of killing a church volunteer at World Changers Church International last month.

Floyd Palmer is accused of fatally shooting Greg McDowell at point blank range while he led prayer during a Bible study.

The 52-year-old suspect was arrested several hours later at Lenox Square and now faces four felony charges, including murder and aggravated assault. At this point, police haven't released any details about a possible motive for the shooting.
